Need help, Game crashing after vehicle mod

Recommended Posts

I changed a few vehicles, put the .wtd and .wft files in the vehicles.img and changed the handling.dat and vehicles.ide as required by the readmes. Now my game crashes during the game load screen, after the game has booted up and tries to load the save. I'm sure I didn't do a necessary step along the way, but not sure what it is. Please help.
